DESCRIPTION

This UPS540e3 in the Powermite3® package is a high efficiency Schottky rectifier that is also RoHS compliant offering high current/power capabilities previously found only in much larger packages. They are ideal for SMD applications that operate at high frequencies. In addition to its size advantages, the Powermite3® package includes a full metallic bottom that eliminates the possibility of solder flux entrapment during assembly and a unique locking tab act as an efficient heat path to the heat-sink mounting. Its innovative design makes this device ideal for use with automatic insertion equipment.

KEY FEATURES

◾ Very low thermal resistance package

◾ RoHS Compliant with e3 suffix part

number

◾ Guard-ring-die construction for transient

protection

◾ Efficient heat path with Integral locking

bottom metal tab

◾ Low forward voltage

◾ Full metallic bottom eliminates flux

entrapment

◾ Compatible with automatic insertion

◾ Low profile-maximum height of 1mm

◾ Options for screening in accordance with

MIL-PRF-19500 for JAN, JANTX, and

JANTXV are available by adding MQ, MX,

or MV prefixes respectively to part

numbers. For example, designate

MXUPS540e3 for a JANTX (consult

factory for Tin-Lead plating).

◾ Optional 100 avionics screening

available by adding MA prefix for 100

temperature cycle, thermal impedance

and 24 hours HTRB (consult factory for

Tin-Lead plating)
